APERION INTIMUS 532 SYSTEM The Aperion 532-LR had some roughness above 1 kHz that’s masked by averaging the response curves. The 533-VAC center speaker has remarkably uniform directivity, with its vertically arrayed midrange/tweeter, so all listeners get sound with the same timbre, though it’s marred by a 5-dB elevation between 1 and 4 kHz and a rapid rolloff below 100 Hz. Likewise, the 432-LR surround speaker had uniform directivity but two 4- to 7-dB peaks at 1.3 and 3.1 kHz.
The S-10 subwoofer had healthy output at 50 and 62 Hz and still useful output at 20 Hz, but dynamic capability fell off at 24 dB per octave below 50 Hz. Although the crossover control is marked from 40 to 150 Hz, the acoustical turnover range covers only 70 to 110 Hz. There was also a moderate 4 dB of crossover/level-control interaction. The grille sometimes rattled when the sub was producing its maximum output.
